6. “CDC recommends wearing cloth face coverings in public settings where other social distancing measures are difficult to maintain (e.g., grocery stores and pharmacies), especially in areas of significant community-based transmission.” CDC: Centres for Disease Control and Prevention, March 2019.

8. “Wearing a non-medical mask...may be helpful in protecting others around you. Face coverings are another way to prevent respiratory droplets from contaminating other people or surfaces.” Government of Alberta: https://www.alberta.ca/prevent-the-spread.aspx

13. “Strict hygiene and public health measures, including frequent hand washing and physical (social) distancing, will reduce your chance of being exposed to the virus. Wearing a non-medical mask or face covering is an additional measure you can take to protect others around you, even if you have no symptoms. It can be useful for short periods of time, when physical distancing is not possible in public settings such as when grocery shopping or using public transit. Wearing a non-medical mask or face covering covers your mouth and nose to help prevent your respiratory droplets from contaminating others or landing on surfaces. Just like our recommendation not to cough into your hands (instead, cover your cough with tissues or your sleeve), a mask can reduce the chance that others are coming into contact with your respiratory droplets. If wearing a non-medical mask or face covering makes you feel safer and stops you from touching your nose and mouth, that is also good. But remember not to touch or rub your eyes.” Government of Canada: https://www.canada.ca/en/public-health/services/diseases/2019-novel-coronavirus-infection/prevention-risks.html#p
